PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT

PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year five), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one, and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect the
conversion of Class B shares into Class A shares six years after purchase. The
since inception returns for Class C shares reflect the conversion of Class C
shares into Class A shares ten years after purchase. See footnote 3 in the Notes
to Financial Statements for additional information. Figures shown above assume
reinvestment of all dividends and capital gains. SEC yield is a calculation for
determining the amount of portfolio income, excluding non-income items as
prescribed by the SEC. Yields are subject to change.

Lehman Brothers Corporate Bond Index is a market-weighted index of
investment-grade corporate fixed-rate debt issues with maturities of one year or
more. Lipper Corporate BBB-Rated Index is an index of funds with similar
investment objectives as this fund. Indexes are unmanaged and do not include any
sales charges or fees. Such costs would lower performance. It is not possible to
invest directly in an index. Source: Lipper Inc.

Fund Report

FOR THE 6-MONTH PERIOD ENDED FEBRUARY 28, 2005

Van Kampen Corporate Bond Fund is managed by the Adviser's Taxable Fixed Income
team.(1) Members of the team include David S. Horowitz, Managing Director of the
Adviser.

MARKET CONDITIONS

The period began in the midst of a slow down in economic recovery brought on by
lower-than-expected and downward revisions to prior payroll gains, resulting in
a downward trend in yields well into the third quarter. Despite this downward
movement, the Federal Reserve Open Market Committee reaffirmed its pledge to
raise the federal funds target rate at a measured pace and did so in its
meetings through the end of the period. This stance was supported by an increase
in economic growth, which picked up steam at the end of 2004.

Economic growth continued during the first two months of 2005. The yield
curve--which measures the difference in yields between short-, intermediate-and
long-maturity Treasuries--flattened further as yields of short- and
intermediate-maturity bonds rose while longer-term yields fell. The bulk of the
increase in yields occurred in February due, in part, to strong payroll numbers,
an upward trend in inflation numbers and testimony by Alan Greenspan indicating
an improving economy.

The generally optimistic economic environment had a positive effect for
corporate bonds. Spreads--which measure the additional yield over Treasuries
demanded by investors for assuming credit risk--tightened over the period,
though not uniformly. Performance at the sector level varied, with gaming and
lodging, energy and insurance among the best-performing sectors of the market.
Each sector benefited from improved earnings for key companies within such
sector. By contrast, automobile companies and their suppliers were among the
worst performers. The electronics sector also suffered.

THE PERFORMANCE FOR THE THREE SHARE CLASSES VARIES BECAUSE EACH HAS DIFFERENT
EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF ALL
DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES CHARGES.
SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE
RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION AND
INDEX DEFINITIONS.

The fund's strong performance relative to the Lehman index was driven in large
part by its focus on medium-quality corporate securities, which boosted its
performance relative to the more broadly constructed Lehman benchmark. Within
its portfolio, the fund benefited from an emphasis on the debt of insurance
companies, which outperformed strongly for the period. The fund also profited
from strong security selection in the paper and energy sectors.

The fund's interest-rate posture produced more mixed results for the period. The
low level of interest rates across the yield curve at the beginning of the
period led us to conclude that they had little room left to fall. As a result,
we kept the fund's overall interest-rate exposure well below that of its
benchmark. This posture was unfavorable to the fund's returns in those months
early in the period when the market rallied, but was more beneficial during
periods of rising rates, such as in January and February.

There is no guarantee the security sectors mentioned will continue to perform
well or be held by the fund in the future.

HOUSEHOLDING NOTICE

       To reduce fund expenses, the fund attempts to eliminate duplicate
       mailings to the same address. The fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling 1-800-341-2911 or writing to Van Kampen Investor Services at 1
       Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, IL 60181. Once Investor
       Services has received your instructions, we will begin sending individual
       copies for each account within 30 days.

PROXY VOTING POLICIES AND PROCEDURES AND PROXY VOTING RECORD

       The fund's policies and procedures with respect to the voting of proxies
       relating to the fund's portfolio securities and information on how the
       fund voted proxies relating to portfolio securities during the most
       recent twelve-month period ended June 30 is available without charge,
       upon request, by calling 1-800-847-2424 or by visiting our website at
       www.vankampen.com. This information is also available on the Securities
       and Exchange Commission's website at http://www.sec.gov.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
cost, including sales charges (loads) on purchase payments of Class A Shares and
contingent deferred sales charge on redemptions of Class B and C Shares; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other Fund expenses. This example is intended to help you understand your
ongoing cost (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 09/01/04 - 02/28/05.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, and $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges. Therefore, the second line
of the table is useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

*   Expenses are equal to the Fund's annualized expense ratio of 0.95%, 1.71%,
    and 1.63% for Class A, B, and C Shares, respectively, multiplied by the
    average account value over the period, multiplied by 181/365 (to reflect the
    one-half year period).

(a) Based on average shares outstanding.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within eighteen months of purchases.
    With respect to shares purchased prior to December 1, 2004, a CDSC of 1% may
    be imposed on certain redemptions made within one year of purchase. If the
    sales charge was included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

(c) As required, effective September 1, 2001, the Fund has adopted the
    provisions of the AICPA Audit and Accounting Guide for Investment Companies
    and began amortizing premium on fixed income securities. The effect of this
    change for the year ended August 31, 2002, was to decrease net investment
    income per share by $.03, increase net realized and unrealized gains and
    losses per share by $.03 and decrease the Ratio of Net Investment Income to
    Average Net Assets by .52%. Per share, ratios and supplemental data for
    periods prior to August 31, 2002, have not been restated to reflect this
    change in presentation.

(d) Amount is less than $.01.

VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Corporate Bond Fund (the "Fund") is organized as a Delaware statutory
trust, and is registered as a diversified open-end management investment company
under the Investment Company Act of 1940 (the "1940 Act"), as amended. The
Fund's primary investment objective is to seek to provide current income with
preservation of capital. The Fund commenced investment operations on September
23, 1971. The distribution of the Fund's Class B and Class C Shares commenced on
September 28, 1992 and August 30, 1993, respectively. The Fund registered Class
I shares on September 1, 2004. There were no sales of Class I shares for the
period ended February 28, 2005.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Fixed income investments are stated at value using market
quotations or indications of value obtained from an independent pricing service.
Investments in securities listed on a securities exchange are valued at their
last sale price as of the close of such securities exchange. Listed and unlisted
securities for which the last sales price is not available are valued at the
mean of the bid and asked prices. For those securities where quotations or
prices are not available as noted above, valuations are determined in accordance
with procedures established in good faith by the Board of Trustees. Futures
contracts are valued at the settlement price established each day on the
exchange in which they are traded. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost, which approximates
market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund invests in repurchase agreements, which are short-term investments
in which the Fund acquires ownership of a debt security and the seller agrees to
repurchase the security at a future time and specified price. The Fund may
invest independently in repurchase agreements, or transfer uninvested cash
balances into a pooled cash account along with other investment companies
advised by Van Kampen Asset Management (the "Adviser") or its affiliates, the
daily aggregate of which is invested in repurchase agreements. Repurchase
agreements are fully collateralized by the underlying debt security. The Fund
will make payment for such securities only upon physical delivery or evidence of
book entry transfer to the account of the custodian bank. The seller is required
to maintain the value of the underlying security at not less than the repurchase
proceeds due the Fund.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis.
Discounts on debt securities purchased are accreted and premiums are amortized
over the expected life of each applicable security. Income and expenses of the
Fund are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and incremental transfer agency costs which are
unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At August 31, 2004, the Fund had an accumulated capital loss carryforward
for tax purposes of $18,983,081 which will expire according to the following
schedule:

<Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and gains on future transactions. All
short-term capital gains and a portion of future gains are included in ordinary
income for tax purposes.

    The tax character of distributions paid during the fiscal year ended August
31, 2004 was as follows:

</Table>

    Net realized gains or losses may differ for financial and tax reporting
purposes as a result of the deferral of losses relating to wash sale
transactions.

F. EXPENSE REDUCTIONS During the six months ended February 28, 2005, the Fund's
custody fee was reduced by $10,476 as a result of credits earned on cash
balances.

                                                                              25

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                      % PER ANNUM
                                                           
First $500 million..........................................     .42%
Next $750 million...........................................     .35%
Over $1.250 billion.........................................     .22%
</Table>

    Effective November 1, 2004, the management fee was reduced from .50% for the
first $150 million, .45% for the next $100 million, .40% for the next $100
million, and .35% for any average daily net assets greater than $350 million.

    For the six months ended February 28, 2005, the Fund recognized expenses of
approximately $21,300 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, counsel to the Fund, of which a Trustee of the Fund
is a partner of such firm and he and his law firm provide legal services as
legal counsel to the Fund.

    Under an Accounting Services agreement, the Adviser provides accounting
services to the Fund. The Adviser allocates the cost of such services to each
fund. For the six months ended February 28, 2005, the Fund recognized expenses
of approximately $17,100 representing Van Kampen Investments Inc.'s or its
affiliates (collectively "Van Kampen") cost of providing accounting services to
the Fund, which are reported as part of "Other" expenses in the Statement of
Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
February 28, 2005, the Fund recognized expenses of approximately $474,800
representing transfer agency fees paid to VKIS. Transfer agency fees are
determined through negotiations with the Fund's Board of Trustees.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are also
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and, to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of approximately $77,800 are
included in "Other" assets on the Statement of Assets and Liabilities at
February 28, 2005. Appreciation/depreciation and distributions received from
these investments are recorded with an offsetting increase/decrease in the
deferred compensation obligation and do not affect the net asset value of the
Fund. Benefits under the retirement plan are payable upon retirement for a
ten-year period and are based upon each trustee's years of service to the Fund.
The maximum annual benefit per trustee under the plan is $2,500.

    For the six months ended February 28, 2005, Van Kampen, as Distributor for
the Fund, received commissions on sales of the Fund's Class A Shares of
approximately $275,500 and CDSC on redeemed shares of approximately $126,700.
Sales charges do not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $223,541,553 and $151,085,671,
respectively.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio or to generate

 28


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued

potential gain. All of the Fund's portfolio holdings, including derivative
instruments, are marked to market each day with the change in value reflected in
unrealized appreciation/depreciation. Upon disposition, a realized gain or loss
is recognized accordingly, except when taking delivery of a security underlying
a futures contract. In this instance, the recognition of gain or loss is
postponed until the disposal of the security underlying the futures contract.
Risk may arise as a result of the potential inability of the counterparties to
meet the terms of their contracts.

    During the period, the Fund invested in futures contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in futures on U.S. Treasury Notes. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the six months ended February 28,
2005, were as follows:

6. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as

                                                                              29


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued

amended, and a service plan (collectively, the "Plans"). The Plans govern
payments for: the distribution of the Fund's Class A Shares, Class B Shares and
Class C Shares; the provision of ongoing shareholder services with respect to
such classes of shares; and the maintenance of shareholder accounts with respect
to such classes of shares.

    Annual fees under the Plans of up to .25% of Class A average daily net
assets and up to 1.00% each of Class B and Class C average daily net assets are
accrued daily. The annual fees for Class A Shares are paid quarterly and the
annual fees for Class C Shares are paid monthly. For Class B Shares, 75% of the
annual fees are paid monthly, while 25% of the annual fees are paid quarterly.
The amount of distribution expenses incurred by Van Kampen and not yet
reimbursed ("unreimbursed receivable") was approximately $2,050,900 and $0 for
Class B and Class C Shares, respectively. These amounts may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, any excess 12b-1 fees will be
refunded to the Fund on a quarterly basis.

    Included in the fees for the six months ended February 28, 2005, are
payments retained by Van Kampen of approximately $501,400 and payments made to
Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately $111,600.

7. LEGAL MATTERS

The Adviser, certain affiliates of the Adviser, and certain investment companies
advised by the Adviser or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of certain investment companies advised by
affiliates of the Adviser; the complaint does not, however, name the individual
Trustees of any Van Kampen funds. The consolidated amended complaint generally
alleges that defendants violated their statutory disclosure obligations and
fiduciary duties by failing properly to disclose (i) that the Adviser and
certain affiliates of the Adviser allegedly offered economic incentives to
brokers and others to steer investors to the funds advised by the Adviser or its
affiliates rather than funds managed by other companies, and (ii) that the funds
advised by the Adviser or its affiliates, including the Fund, allegedly paid
excessive commissions to brokers in return for their alleged efforts to steer
investors to these funds. The complaint seeks, among other things, unspecified
compensatory damages, rescissionary damages, fees and costs.

    The Adviser and certain affiliates of the Adviser are also named as
defendants in a derivative suit which additionally names as defendants certain
individual Trustees of certain Van Kampen funds; the named investment companies,
including the Fund, are listed as nominal defendants. The complaint alleges that
defendants caused the Van Kampen funds to pay economic incentives to a
proprietary sales force to promote the sale of proprietary mutual funds. The
complaint also alleges that the Van Kampen funds paid excessive commissions to
Morgan Stanley and its affiliates in connection with the sales of the funds. The
complaint seeks, among other things, the removal of the current Trustees of the
funds, rescission of the management contracts for the funds, disgorgement of
profits by Morgan Stanley and its affiliates and monetary damages. This
complaint has been coordinated with the consolidated complaint described in the
preceding paragraph. Plaintiff has sought leave to file a second amended
derivative compliant that alleges that the Adviser permitted or recklessly
disregarded market timing and late trading in its proprietary mutual funds in
order

 30


VAN KAMPEN CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS -- FEBRUARY 28, 2005 (UNAUDITED) continued

to increase assets under management and fees. However, pursuant to an agreement
between the parties, that plaintiff's proposed second amended derivative
complaint was withdrawn and the allegations regarding market timing and late
trading asserted therein were filed in a separate complaint and coordinated with
other cases related to market timing that have been centralized in a federal
court.

    The defendants have moved to dismiss each of these actions and otherwise
intend to defend them vigorously. While the defendants believe that they have
meritorious defenses, the ultimate outcome of these matters is not presently
determinable at this early stage of litigation, and no provision has been made
in the Fund's financial statements for the effect, if any, of these matters.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

                                                                              31
